These are large, hot balls of gas that emit light.
What is a star?
This graph compares temperature and luminosity of all stars.
What is the HR Diagram?
These are dark, cool spots on the sun.
What are sunspots?
This is the way that the sun rotates.
What is differentially? (counterclockwise, faster at the equator, & slower at the poles)
This is how long it takes sun light to reach Earth.
What is 8 minutes?
This is the center of the sun's atmosphere.
What is the chromosphere?
As seen on the HR diagram, these colored stars are the hottest.
What are blue stars?
The energy in the radiation zone is transferred through these.
What are electromagnetic waves?
A small star is know as this.
What is a dwarf star?
This is another word for brightness.
What is luminosity?
This is the name describing the brightness of a star as seen from Earth.
What is a Apparent Magnitude?
On the HR diagram, the temperature is on this axis.
What is the x-axis?
This process occurs in the core.
What is nuclear fusion?
These numbers represent the brightest stars.
What are lowest numbers?
When energy erupts from the Sun’s surface, these features frequently result.
What are solar flares and prominences?
This is the zone in Sun where heat rises and cool gas sinks.
What is the convection zone?
On the HR diagram, the luminosity is on this axis.
What is the y-axis?
This might change depending on the distance to a star.
What is apparent magnitude?
This is the order of colors of stars from coolest to hottest.
What is red, orange, yellow, white, blue?
These stars can be listed from brightest to dimmest using the following types: white dwarfs, blue giants, main sequence stars, red giants, supergiants.
What are blue giants, red giants, supergiants, main sequence, white dwarfs?
These are clouds of gas that make loops and jets extending from the corona.
What are prominences?
These stars are the brightest AND the hottest.
What are blue giants?
This is the order of the layers of the Sun from the Center to the Outside.
What is the core, radiation zone, convection zone, photosphere, chromosphere, corona?
This is the name of the stars that have basic, medium, temperature and luminosity.
What are Main Sequence Stars?
Two stars have the same apparent magnitude as seen from Earth. Star A is 33 light years away, Star B is 346 light years away. This star has a smaller absolute magnitude.
